Abstract (en)
A reflectometer which uses an integrating cavity interposed between a light source and a test element. The cavity has enhanced efficiency by reason of its construction wherein a diffusely-reflecting surface is connected at opposite edges to mirrored surfaces that reflect back to the diffusely-reflecting surface at least the majority of diffusely-reflected rays that are non-aligned with selected rays from the diffusely-reflecting surface that impinge unimpeded on the test element.
